Synthetic fuels from Lurgi coal pyrolysis

Parallel to work on the devolatilization of coal, a process was also developed for the cracking of hydrocarbons ranging from crude oil to naphtha to produce olefins, using sand as a circulating heat carrier. For this purpose a pilot plant with a capacity of 1 ton/h of feed was developed near Leverkusen. This project led to the commercial application of the Lurge-Ruhrgas Process in six sand crackers in different parts of the world. Numerous pilot plants with oil shales and tar sands have shown that the process is suitable for treating these raw materials, as well. 2 figures, 7 tables.
